Frequently Asked Questions
Q: How does the USB desktop evaporative air cooler work?
A: The cooler draws warm ambient air through its fan, passes it over water absorbed by the internal evaporative pad, and releases a fine cool mist into the room. This evaporative process lowers the temperature of the surrounding air, creating a refreshing breeze. For an even cooler effect, simply add ice cubes to the 900mL water tank.
Q: How long does the 900mL water tank last?
A: On a full tank, the cooler provides approximately 3 hours of continuous misting and cooling at normal spray settings. Runtime may vary slightly depending on the fan speed and spray intensity selected.
Q: What do I need to power this USB air cooler fan?
A: It is powered via a standard USB connection (voltage under 20V). You can plug it into a laptop USB port, a USB wall adapter, a power bank, or any USB hub — making it highly portable and versatile for home, office, or travel use.
Q: Is the USB desktop air cooler noisy?
A: No — the cooler is designed for low-noise operation, so it is well-suited for offices, study areas, and bedrooms where a quiet environment is important. The 3-speed settings let you choose the level of airflow that best suits your comfort and noise preference.
